Maruti Suzuki India — Rust occurred at various parts of the body

Address:

Morbi

I, Amit Ranjan purchased Alto K10 Vxi in the year 2018 and in just 4 years of span got severe rust on several external body parts which makes my car look absolutely absurd. I, have been provided with additional warranty of 1lac kms during the purchase of my car from Perfect Maruti Suzuki dealer at Morbi 363641. Kindly guide me for the necessary option for repair of my car and get rid of rust which gives very bad look to my car which has travelled just 42000 kms only.
